Abstract: 740,833. Automatic bobbin changing in looms. BEAUMONT, F., and GLEDHILL, E. May 26, 1954 [April 22, 1953], No. 11030/53. Class 142 (2). When bobbin changing is initiated, a slide 9 is moved rearwards so that a hook 1 enters the next-to-the-top shuttle box cell (which is then empty). After bobbin changing, the slide returns to its forward position, during which movement a lever 13 encounters the breast beam 7 and raises the hook, whereby the weft of the ejected bobbin is drawn into clamping jaws 23, 25. The jaws were opened, during the forward movement, by a cam 37 on the slide 9 riding under a bracket 35 on the pivoted jaw 25 and are allowed to close when the slide is fully forward. On the next rearward movement of the slide, the cam 37 pivots, when it encounters the bracket 35, until it contacts a stop (not shown) so that the jaw 25 is lifted only slightly to allow the weft thread to slide down the jaws into a notch 27 in the jaw 25.

[Class 89 (i)] The parts a, b, Fig. 2, of a lock-nut, each tapped for the bolt 1 are separated by a cage of balls 6 bearing on thrust washers 7 all contained in a counterbore in the part b. A spring 4 contained in an annular recess in the part a bears on the ball-race through a washer 8 keyed to the skirt 11 of the part a. The radial end 13 of the spring engages a slit in b and the axial end 12 passes through a hole in a, to which it may be soldered at 15. The pawls have index marks to-show the relative position in which they both screw on the bolt and in this position the spring is tensioned to tend to tighten one part against the other. The Specification as open to inspection under Sect. 91 describes a modification in which the washers 7 and 8 are replaced by formed races 15, 16, Fig. 4 (Cancelled), the race 15 being shaped to be held in the part b by the spring 9. This subject-matter does not appear in the Specification as accepted.

Title: Improvements in means for facilitating the changing of gears on motor vehicles
Filed: 1928-04-17
Abstract: 309,740. Morris, J. N., Bone, C. C., and Scott, M. D. April 17, 1928. Facilitating changing speed.-Means comprising differential and electrical gear are provided for governing the engine upon a vehicle at a speed suitable for a noiseless change of gear. An auxiliary gearpox shown in Fig. 1 is provided with shaft 1 driven from the tail shaft of the usual changespeed gear, and shaft 2 driven from the engine shaft. Sets of differential gearing 8 are provided so that for each ratio in the main gear box, one of a number of discs 6 is brought to rest. The engine is governed so as to maintain at rest the disc 6 corresponding to the gear ratio to be rendered operative. A ball 15, Fig. 5, is held so as to run in grooves in the edge of disc 6 and in a spring-pressed curved arm 11. If the disc 6 turns clock-wise, the ball 15 is carried with it, separating the arm 11 and closing an electric contact 18 leading to terminal 20. This acts on magneto or throttle to slow down the engine. When the disc 6 turns anticlockwise, the ball 15 returns to the position shown, which breaks contact 18 and allows the engine to speed up. There is a terminal 20 for each speed, and selection is made amongst them by a miniature gate 40<1>, Fig. 2, carried by the main change lever 38. Sleeve 39 is turned and slid by wrist movements so as to bring an earth contact 43 into engagement with four contacts 44, one for each speed. To effect a change, the change lever 38 is moved to neutral and the wrist selective movement carried out. The main clutch is engaged and the accelerator depressed. The engine then comes to and stops accelerating at the speed when a noiseless change can be effected by moving lever 38. In an arrangement alternative to that shown in Fig. 1, the discs 6 are side-by-side on nested sleeves driven by stepped planet gears.

Title: Gain control circuits

Filed: 1941-09-05
Abstract: 545,866. Volume controlling in repeaters. STANDARD TELEPHONES & CABLES, Ltd. Sept. 5, 1941, No. 11367. Convention date, Sept. 14, 1940. [Class 40 (iv)] In a repeater system in which the gain of the amplifiers is controlled by a pilot current, arrangements are made for stabilizing the gain of each amplifier at some value less than the maximum if the pilot current fails. As shown in Fig. 1, the gain of the transmission-path amplifier A is controlled by a thermistor T connected to the e-circuit and heated by the output of an oscillator O, the grid of which is biassed by rectified pilot current. The characteristics of the oscillator are controlled by a suitable choice of the value of a condenser K and of its point of connection on resistance 14 and may be such that as the bias falls with a fall in pilot current level, the output of the oscillator and therefore the gain of the amplifier A increase up to a point and are thereafter reduced so that if the pilot fails altogether the amplifier is stabilized at a comparatively low gain. In a modification, resistance r2 is omitted and resistance r3 is made variable to give the necessary adjustment. In other arrangements, failure of the pilot current operates a relay which may stabilize the oscillator output at a suitable value or replace it in the heater circuit by a generator with a fixed output or may substitute a fixed resistance for the thermistor in the #-circuit.

Abstract: 1504722 Filter press EBERHARD HOESCH & SOHNE 19 March 1975 [30 March 1974] 11502/75 Heading BID A filter press comprises a closing pressure regulator 7', 8' actuated by a sensing arm 6' which moves with a filter plate on end plate of the press. The pressure regulator adjusts the pressure (e.g. in a hydraulic cylinder having ram 27) applied to press the plates together so that the plates are neither too close nor too far apart. Arm 6' operates a series of (e.g. three) switching plungers (10, 11 and 12 Fig. 2 not shown) which control flow of fluid from pump 28 to a piston 27. If plates 22 are too close, or are forced too far apart by injected fluid to be filtered then hydraulic fluid is transferred to adjust them to a median position. Fig. 3 shows a continuous belt filter cloth entrained about the plates, and driven by two hydraulic synchronised motors 26 and 32. Fig. 1 shows a horizontal non-belt type press.

A photographic material comprises a layer containing nuclei which are capable of acting as centres for physical development and, in the same layer or in an adjacent layer (1) a polysulphide which on exposure to actinic radiation forms a substance which destroys or reduces said capability e. g. bis (p-tolyl) trisulphide or (2) an organic azide which on exposure to actinic radiation releases N2 with the formation of a free radical e.g. 4-azido-3-methyl-N, N-diethyl aniline, and a compound which reacts with said free radical thereby to form or to release a physical development inhibiting substance which destroys or reduces said capability. The compounds reacted with the organic azido to form or release the development inhibiting substance are the development inhibitor releasing couplers (DIR couplers) of Specifications 932, 272 and 953, 454, e. g. 1-hydroxy-4-(2'-amino-4'-methyl phenylazoxy)-N-(#-(2", 4"-di-t-amylphenoxy) butyl)-2-naphthamide used in Example 1.

The DIR coupler may be incorporated in the binder of the layer containing nuclei by means of a water immiscible solvent B.P. #. 175‹C. e.g. tricresyl phosphate. The exposed material may be developed by (1) contacting with an unexposed silver halide emulsion in the presence of a silver halide solvent and a silver halide developing agent (2) swabbing with an aqueous silver salt e. g. AgNO3 solution and then immersion in a silver halide developer and (3) employing a light-sensitive material containing a complex silver salt e. g. a silver thiosulphate or 4, 5-dihydroxy hexahydro-1, 7-dioxa- 7a-hydroxymethyl-3-azoindene-2-thione complex and developing with a reducing agent e. g. silver halide developer.
